[clean-list] fopen of named pipe fails with "IO Error: FOpen: seek to end of file failed"

[David C. Norris]

in shell:
$ mkfifo pipe

namedpipe.icl:

module namedpipe

import StdEnv

Start :: *World -> *World
Start world
    # (writeok, pipe, world) = fopen "pipe" FAppendText world
    | not writeok            = abort "Unable to open 'pipe'"
    | otherwise              = world


Does StdFile support use of named pipes on linux?  What options exist 
for implementing interprocess communication using Clean on linux?
